JPH06185271A - Sound insulating part for gap of sliding door - Google Patents

Abstract

PURPOSE:To smooth sliding in the case of opening and shutting of a door by using adhesive-backed ultra-polymer polyethylene tapes for sliding doors such as aluminum sashes, etc., and using polyurethane foam, etc., for a static window frame. CONSTITUTION:Two adhesive surfaces are paralleled with each other to provide compressive force for sliding doors 3a and 3b such as such as aluminum sash windows, etc., and a sliding surface is constituted of an aluminum sash and an ultral polymer polyethylene film 2c. At that time, adhesive or double faced adhesive tape 2c backed polyurethane foam 2b is used for the lower part of a static window frame. The two adhesive surfaces are at right angles to each other to use the ultra-polymer polyethylene tape 2c for the sliding surface. According to the constitution, an infiltration draft between the sliding doors 3a and 3b is prevented, and sound insutating effect can be increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to parts for preventing drafts and gaps in sliding doors such as aluminum sashes.
Mainly about retrofit parts.

[0002]

2. Description of the Related Art Of the gaps that are conventionally created in sliding doors, about 9
Regarding the soundproofing of the gap of the sliding surface by 00 mm, in the aluminum sash maker product, since the gap is generally large in the upper part, as shown in FIG. The seal structure is adhered to the aluminum sash 2. Since the gap is long and small in the lower part, this kind of sealing measure is often omitted.

If there is no measure for sealing the lower part of the aluminum sash, or if there is no measure for sealing both the upper and lower parts of the aluminum sash, citizens will use commercially available sealing materials such as polyurethane foam for measures against drafts. .

Next, the operation will be described. When the sealing material is velvet-like, when the window is closed, the sound waves repeatedly collide with the thin bristles of multiple layers, so that it works so as to attenuate, but since the gap is open inside and outside, the sound insulation is limited. There is. When the window is opened and closed, the long hair flutters in the direction opposite to the closing direction and closes lightly.

In the case where the sealing material is polyurethane foam, the sound wave travels through a small and tortuous air path in the polyurethane foam when the window is closed, so that the number of reflections is greatly attenuated. When a window is opened and closed, it is strongly resisted by friction and requires force, so girls and children dislike it.

[0006]

Since the conventional gap seal is constructed as described above, the sound insulation performance is not so great, and in a condominium in an urban area, changes such as an increase in traffic volume and an increase in trucks after the building is completed. There was a need to add soundproofing measures, but there were no suitable parts. Further, when a commercially available draft preventive seal is diverted, there is a drawback that it is disliked because the frictional force increases when the door is opened and closed.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a seal which can increase the soundproof effect and which does not increase the frictional force when the door is opened and closed.

[0008]

A part for preventing drafts of a sliding door and soundproofing a gap according to the present invention comprises a combination of a low friction coefficient tape with an adhesive and an adhesive or a soft foamed plastic material with an adhesive. .

[0009]

The function of the present invention for preventing drafts in a sliding door and for soundproofing a gap is that the low friction coefficient tape provided on the surface does not require a force to open and close the sliding door, and functions to prevent drafts and soundproof a gap in a sliding door.

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is the lower part of the stationary window frame, 2 is the gap soundproofing part of the present invention adhered to the stationary window frame, 2a is double-sided adhesive tape, 2b is foamed polyurethane foam, 2c.
Is an ultra high molecular weight polyethylene tape with an adhesive, 3a is the right side of the aluminum sash glass moving door, and 3b is the left side of the aluminum sash glass moving door.

[Operation of Embodiment 1] In this case, both adhesive surfaces are characterized by receiving a compressive force. The sliding surface is composed of an aluminum sash and an ultra-high molecular weight polyethylene film, and since the friction coefficient is an extremely low value of about 0.1, a small force is required to close the door. Of course, the soundproofing effect is increased and there is no draft.

Example 2. In the first embodiment, the two adhesive surfaces are in a positional relationship parallel to each other, but in the second embodiment, the two adhesive surfaces are in a relationship of forming a right angle with each other as shown in FIG. In FIG. 2, 4 is the upper part of the stationary window frame, 2 is the gap soundproofing part of the present invention adhered to the stationary window frame, 2a is a double-sided adhesive tape, 2b is foamed polyurethane foam, 2d is an ultra high molecular weight polyethylene tape with adhesive. It is provided on the surface perpendicular to the other adhesive surface. 3a is the right side of the aluminum sash glass moving door, and 3b is the left side of the aluminum sash glass moving door.

The operation of Example 2 differs from that of Example 1 in that the adhesive of the ultra-high molecular weight polyethylene tape with adhesive receives a compressive force, but the double-sided adhesive tape 2a and the foamed polyurethane foam 2b have shearing force. Is the point to receive.
The other operations are the same as those of the first embodiment, and will be omitted below.

[0014]

As described above, according to the present invention, a low friction coefficient plastic tape with an adhesive and a plastic with an adhesive or a double-sided adhesive tape are used as parts for preventing drafts in a sliding door such as an aluminum sash window and for soundproofing gaps. Since a composite material consisting of two-way adhesion with a soft foam material is used,
When opening and closing the door, it slides well and does not require force, increasing the soundproofing effect and preventing drafts.

2. Description of the Related Art Of the gaps that are conventionally created in sliding doors, about 9
Regarding the soundproofing of the gap of the sliding surface by 00 mm, in the aluminum sash manufacturer's product, since the gap is generally large at the top and the sound wave propagation distance is short, a thick string of velvet-like cloth with long hair is made of aluminum. The seal structure is adhered to the glass door. Since there is a narrow gap at the bottom and the sound wave propagation distance is long, this kind of sealing measure is often omitted.
